To all whom t may concern.'

Be it known that I, MICHAEL P. FLEMING, a citizen of the United States,and a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented a certain new and useful Supplementary tress, ofwhich the following is a specification.

My invention relates to a new and useful mattress support, and theobject of this invention is the production of a mattress support orsupplementary mattress which is adapted to give stiffness to an ordinarymattress and prevent the latter from being pressed into the springs of abed thereby making small depressions which are uncomfortable to users ofthe mattress.

A further object is the production of a simple and effective mentioned.

Other objects will appear hereinafter.

With these objects in view, the invention consists in the combinationsand arrange-..

ments of parts hereinafter described and claimed.

T he invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which,

Figure l is a view, supplementary mattress embodying my invention,showing show the break therein, Fig. 2 is an enlarged transverse sectionof the same, and Fig. 3 is an enlarged fragmental longitudinal section.

The preferred form of construction as illustrated in the accompanyingdrawing comprises a frame made up of rigid end members 4 and rigid sidemembers 5 arranged on edge and secured together in any approved mannerin rectangular form. EX- tending longitudinally between the ends 4 areribs 6 of rigid material spaced apart and secured to said ends by meansof nails 7, or their equivalent passing through the ends and thecovering to be vmentioned hereinafter. Spaced apart and loosely mountedbetween the ribs 6 are short ribs 8. The ribs 8 are also of rigidmaterial and are held in position by means of the lcovering 9 andfilling material l0 of the supplementary mattress. The covering 9 andfilling material 10 are the ordinary substances for like purposes inordinary mattresses. The covering 9 is secured tothe device by meansMat'- i device of the character in perspective, of a one end slightlylowered to of stitchings l1 passing through said covering and thefilling material 10. The stitchings 11 are similarto the ordinarystitching used inv mattress-construction.

. In smaller sizes of bedsY my supplementary mattress in one piece, butin larger sizes such as illustratedI prefer to divide the supplementarymattress in two sections and hingev these sections together by means ofa portion lZf the vlower side of covering 9, see Figs. 1` and B. Thisprovides a means for doubling the mattress into smaller space and ientfor handling. to the frame of the vice from givingv readily in smallareas into a bed spring kon which it Vmay be used, and the ribs 8provided for slight movement, since they are not -secured to the ribs 6,permitting slight that in use, the device is yieldable and still firmenough toy prevent the spring from4 being depressed unevenly under theweight of a person.

making it more conven- The ribs 6 being secured v '6o I prefer to makedevice prevents the den flexibility to the device so4 While I haveillustrated and described the Y preferred form of construction forcarrying my invention into effect, this is capable of variation andmodification without departing from the spirit of the invention. I,therefore, do not wish to be limited to the precise details ofconstruction set forth, but desire to avail myself of such variationsand modifications as vcome within the scope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. vA supplementary mattress comprising av rigid rectangular-frame;parallel spaced rigidv ribs extending across and secured at their endsto said frame: a covering enveloping said frame; andv filling materialbetween said ribs lin said covering, substana rigid rectangular frame; acovering enveloping said frame; parallel spaced rigid ribs in and havingtheir ends secured to said *said ribs f-andffsaid filling frame, theedges of said ribs engaging said covering; short spaced parallel rigidribs in said frame and between said first mentioned ribs and at rightangles tothe latter; 'and filling material between said ribs yin saidcovering, substantially as described.

4. A supplementary mattress comprising a rigid rectangular frame; acovering enveloping said frame; parallel spaced rigid ribs in and havingtheir ends secured to said frame,Y the edges of said ribs engaging' saidcovering; short spaced parallel rigid ribs in said frame and betweensaid first mentioned ribs and at right angles to the latter; Allingmaterial between-"said ribsin said covering; and ties vpassingthroughsaid vfilling material andcovering binding the'latterf against imaterial,"substan tially `as described.

'5. iai-supplementary mattress comprising arigid rectangular frame; acovering enveloping V`said frame; Va `plurality of' spaced rigidribs-'eXten'ding longitudinally vof' vsaid frame; nails passing through`said covering andl frame and into the ends 'off-said ribs; `aYplurality of short: spaced rigid ribs disposed Atransverselyiofsaidframe A and positioned between 'said first Vmentioned ribs andthe"sides 'of' 'said :frame filling material inV said covering and betweensaid ribs and frame a rigid vref'ztangular substantially portions;andties th'ro'u-ghsaid filling material and covering binding the latteragainst said frame and ribs, substantially as described.

6. A supplementary mattress comprising a rigid rectangular frame, aplurality of ribs arranged within said frame, certain of' said ribsbeing rigidly connected to said frameand the remaining ribs being'adapted for limited vertical movement, a filling arranged between saidlribs and a cov'eringfenveloping said frame'and filling, 'substantiallyas' described.

7. A' supplementary `inzittr'ess comprising frame, parallel spaced rigid'ribs fixedly secured ywithin said frame, short 'spaced parallelk ribsarranged between the .first mentioned ribs and at substantially rightangles theretogt'he last mentioned ribs Vhaving' limited verticalmovement, "a filling l50 arranged between said ribs, and a covering,

as described.
